Hi Scott,
I too have watched the majority of my stock of i1 Displays go bad,
and some are only a few months old. In contrast, the i1 Pros (which
I've owned for more than 3 years) are still able to produce excellent
display and print profiles.
Not yet being the color geek (and I truly wish I was) that all of you
are, I too base my observation that the i1 Displays have gone bad, on
the images I see on screen, just as Andrew recommended, although I
realize that this is not at all scientific and obviously very biased
to my perception of color.
To be more specific, we own approximately 20 i1 Displays and 7
i1Pros. I use these once a week, all at the same time, to calibrate
two labs of 20" Apple Cinema LCD Displays. In total, I make 20
profiles in one lab and 34 in the other, and have been doing this for
about 3 years. This gives me plenty of opportunity to put the same
image up on each screen and visually evaluate the quality of the
profiles. I no longer use the i1 Displays because they are simply not
trustworthy (consistent), although my much older i1 Pros are still
fantastic. I now only use the i1 Displays to teach our students about
display profiling for which they are invaluable.
Further, I too have observed that the bad i1 Displays produce a
magenta shifted profile, keenly visible in the highlights.
Finally, I've used both i1 Match, Profilemaker and CEDP to generate
my screen profiles. CEDP has consistently been the only application
able to give me the same "look" on every screen in the lab. By this,
(and please do excuse my lack of correct terminology) I mean that
when I ask for a set of criteria, CEDP produces that criteria on
every screen/computer so that my end result is a lab that looks
consistent from system to system and produces predictable prints.
Andrew, for what it's worth I paid for my copies of CEDP.
Obviously my observations are those of a novice user but I thought
I'd share them anyway.
Thanks,

Our internal testing using DTP94s and EyeOnes interchangeably has
yielded very good results using CEDP.
Keep and eye on those EyeOneDisplays. I have seen about 8 of them
go bad over time. Sometimes they go horribly bad overnight and
sometimes it happens slowly. A magenta cast in a display's
calibrated whitepoint is the sign to look for.
I prefer to LOOK at images.
Me too - that's always the bottom line that maters more than
anything else. I have come to recognize certain trends in CEDP's
validation results that translate into positive or negative viewing
conditions. Same with MP's round trip numbers. After a while you
come to recognize certain trends and get a "feel" for the results.
So for me, there is some value.
As for colorimeters I have found the EyeOne Display (1and2) and
Spyder1 to be inconsistent
How many samples of each, based on what, over what time span?
Over 100 EyeOneDisplays and a few dozen Spyders since they were
introduced. Although I own several of each I have an extensive
client base whose devices I also use and compare to my own when I
am onsite (which is 4-6 days a week). EyeOne Displays are pretty
consistent with each other when they are in good but a small
percentage are bad out of the box and some go bad over time. I have
not yet seen a bad DTP94.
